srcu: Rename srcu_check_read_flavor_lite() to srcu_check_read_flavor_force()

Browse Source 
This commit renames the srcu_check_read_flavor_lite() function to
srcu_check_read_flavor_force() and adds a read_flavor argument in order to
support an srcu_read_lock_fast() variant that is to avoid array indexing
in both the lock and unlock primitives.
